In simple terms, arteries carry oxygen-rich blood from the heart to the tissues, veins return oxygen-depleted blood to the heart.

Deep veins return blood directly to the heart and are in the center of the leg, near the bones. Superficial veins are closer to the surface and have less support from surrounding muscles and other tissues than the deep veins have.

Varicose veins are swollen and twisted veins just below the surface of the skin. Because of faulty valves elsewhere in the leg, "the veins" hold more blood and "are" at higher pressure than normal. This increase in blood volume and pressure causes the veins to swell giving their characteristic appearance.

The normal function of veins is to carry blood back to the heart. To prevent blood from flowing in the wrong direction, veins have numerous non-return valves. If the valves fail, blood flows the wrong way in the superficial veins and back down the leg. This results in surface tributary veins enlarging and becoming varicose.

Gravity. The distance from the feet to the heart is the furthest blood has to travel in the body. The vessels in the leg therefore experience the greatest back pressure, and if vein valves can’t hold it, the backflow of blood will cause the surface veins to swell.

Everyone! However, the main causes are genetic and gender. Women are nearly twice as likely to suffer as men. People with past vein diseases, new mothers, overweight individuals and people with jobs or hobbies requiring extended standing are also at increased risk.

Aside from the familiar surface appearance of rope-like varicosities, there may be significant leg pain and feet and ankles may swell towards the end of the day, especially in hot weather. Varicose veins can get sore and inflamed, causing redness of the skin around them. In some cases, patients may develop venous ulcerations.

EVLT stands for EndoVenous Laser Treatment.

The laser energy damages the vein walls shrinking them and closing the faulty vein so that the blood cannot flow through it. This eliminates vein bulging at its source.

No. After treatment, the blood in the faulty veins will be diverted to the many normal veins in the leg.

The most common complication patients see is numbness that usually corrects itself in a timely manner. However, as with any surgery, there are risks and further possible complications. We can discuss this with you more in depth at your initial medical exam and consultation.
